[SOLVED] new surplus nmcli device and wifi not working

Hello,

recently my wifi stopped working. According to my nm-applet there was a connection, however

$ ping 8.8.8.8

ping: connect: network not accessible

translated output

I discovered a surplus device (p2p-dev-wlp3s0) in nmcli:

$ nmcli device

DEVICE          TYPE      STATE            CONNECTION
enp0s31f6       ethernet  connected       Ethernet-Verbindung 1
wlp3s0          wifi      connected        khNet HBW
p2p-dev-wlp3s0  wifi-p2p  nicht connected  --
lo              loopback  not managed  --

translated output

which has no physical correspondence and does not show up in

$ ip link

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: enp0s31f6: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP mode DEFAULT group default qlen 1000
    link/ether e8:6a:64:33:9c:34 brd ff:ff:ff:ff:ff:ff
3: wlp3s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP mode DORMANT group default qlen 1000
    link/ether 18:1d:ea:c5:06:43 brd ff:ff:ff:ff:ff:ff

So I assume this device is responsible for things getting mixed up. I have no idea in how this device was created and i would really like it to be removed. However, my primary goal is to get network manager running again. Any ideas by someone? I would be very glad!

For completeness some more output:

Re: [SOLVED] new surplus nmcli device and wifi not working

Post the journal, this additional device is irrelevant and mostly normal and read this thread  posted a few minutes ago: https://bbs.archlinux.org/viewtopic.php?id=251861

Re: [SOLVED] new surplus nmcli device and wifi not working

Thanks for the help!

Exchanging the dhcp client as suggested in the other thread solved the problem. Did not thought of it to be related, since the network manager indicated to be connected and wired networking worked.
